Today, Teacher Yang walked into the classroom with a straight face, threw the book on the podium, and the class that was originally noisy and noisy like a vegetable market suddenly became silent, and everyone was shocked by the teacher's behavior. After condensing for a few seconds, the teacher named Huang Qianqian, and then took out her weekly diary from the notebook and said:"This time, the weekly diary was written in a daze, especially Huang Qianqian, who was very poorly written.

After finishing speaking, I asked Huang Qianqian to come up and get the notebook. I was very surprised, and everyone too, how could a person who usually writes very well be rated by the teacher as the worst writer in the class? We were all shocked, some were scared.

The teacher called everyone up one by one and talked about his expressions, moods, and movements today.
